Trump: Anti-Semitism is 'horrible' and 'has to stop'

President Donald Trump on Tuesday condemned anti-Semitism in his strongest terms so far after criticism that he failed to respond specifically to recent threats at Jewish community centers.

"I will tell you that anti-Semitism is horrible, and it's going to stop and it has to stop," Trump told MSNBC in an exclusive interview, saying he denounces prejudice "wherever I can."

The statement comes amid a wave of threats to Jewish community centers around the country. Federal authorities were investigating threats made to 10 facilities on Monday, according to NBC News. No one was injured and the calls appear to be hoaxes, NBC said.

He also failed to denounce threats in last week's joint press conference with Israeli Prime Minister Benjamin Netanyahu.

Trump later condemned anti-Semitism in a statement following his tour of the National Museum of African American History and Culture in Washington.

"The anti-Semitic threats targeting our Jewish community and community centers are horrible and are painful and a very sad reminder of the work that still must be done to root out hate and prejudice and evil," Trump told reporters.

In one instance, vandals toppled headstones of about 170 graves at a historic Jewish cemetery in St. Louis, Missouri.

Asked Tuesday why Trump did not explicitly denounce the threats when he was given a chance last week, White House press secretary Sean Spicer argued that Trump has "been very clear over and over" about his administration's push for unity. He said that Trump may not need to respond to every incident because "he's spoken very forcefully" against prejudice.
